quad2tri

Below is a demonstration of the features of the quad2tri function

Contents

Syntax

[varargout]=quad2tri(varargin);

Description

Examples

clear; close all; clc;

% Plot settings
fig_color='w'; fig_colordef='white';
fontSize=15;
faceColor='b';
faceAlpha=1;
edgeColor='k';
edgeWidth=1;

Examples

Example: Converting a quandrangulated surface to a triangulated surface

[X,Y,Z]=peaks(25);
[F,V]=surf2patch(X,Y,Z);

Convert triangular faces to quadrilateral faces

[Ft,Vt]=quad2tri(F,V);

Visualisation
